CnQF is a feature that will dynamically adjust performance and power consumption based upon OEM specified metrics on supported systems.
This is targeted for 6.1.
platform/x86/amd/pmf: Add support for CnQF

platform/x86/amd/pmf: Add sysfs to toggle CnQF

Documentation/ABI/testing/sysfs-amd-pmf: Add ABI doc for AMD PMF
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/commit/?h=for-next&id=1590ac2c6615329d30e25753e03c295cdaf2ae44 |
[SRU Justification]
[Impact]
Missing AMD CnQF that will dynamically adjust performance and power
consumption based upon OEM specified metrics on supported systems.
[Fix]
Three commits from linux-next to be backported to oem-6.0 and above.
[Test Case]
To enable this in AMD Phoenix CRB:
BIOS: AMD PBS > AMD PMF Settings, enable function 11/12 & flag=1
And feature enabled message should appear in dmesg:
[ 3.203628] amd-pmf AMDI0102:00: registered PMF device successfully
Access via sysfs:
root@test:/sys/devices/platform/AMDI0102:00# cat cnqf_enable
on
[Where problems could occur]
This is a new feature and will probably receive some more fixes in the
future. So far we have little, in both kernel and userspace, runtime and
testing, involved.
[Other Info]
This series depends on AMD PMF support in bug 1987670. And since these
patches targets v6.1 and AMD phoenix target oem-6.0, only oem-6.0 and
unstable is nominated for fix.
